USB reset-resume quirk prevents the device from runtime suspending,
which increases power usage.

With the patch, the power consumption decreases 0.5W.
The tested machine doesn't need the quirk to make btusb work.

Update the btusb reset-resume quirk with a DMI based version, which can
be more specific.

[Regression Potential]
Everthing is in mainline, and I haven't seen any new report about this
issue for some time.
